To Reproduce Run visualvm.exe Get this error

Screenshots If applicable, add screenshots to help explain your problem.

You can specify JDK with --jdkhome option. To do so run visualvm from cmmand line: visualvm.exe --jdkhome <path_to_jdk> See visualvm.exe --help for more info about command line arguments.

I tried but I get an error:

Cannot locate java installation in specified jdkhome:
c:\Java\jdk-21_windows-x64_bin
Do you want to try to use default version?

[thurka]

It looks like c:\Java\jdk-21_windows-x64_bin does not contain JDK installation. What is the content of c:\Java\jdk-21_windows-x64_bin directory?

I tried specifying the path in several different ways, but it didn't help.

folder c:\Soft\Games\jdk-21_windows-x64_bin\jdk-21.0.3\bin

As correctly stated by VisualVM c:\Java\jdk-21_windows-x64_bin is not JDK home directory. Based on your response above, please use c:\Soft\Games\jdk-21_windows-x64_bin\jdk-21.0.3 as JDK home. So you will run visualvm using command below:

visualvm.exe --jdkhome c:\Soft\Games\jdk-21_windows-x64_bin\jdk-21.0.3

I realized my mistake - I used quotes for jdk path.
